WILHELM BEER, OF BOCHUM, GERMANY.

I STORAGE OF LARGE QUANTITIES OF INFLAMMABLE LIQUIDS ANTS fliALCTIONAL DELIVERY THEREOF.

Application filed. May 27,

T 0 all whom it may concern:

Be it known that I, NILHELM Hank, a citizen of the German Empire, and a resident of Bochum, Germany, have invented certain new and useful Improvements in Storage of Large Quantities of lnflammable Liquids and Fractional Delivery Thereof, of

which the following is a. specification.

This invention relates to the storage of inflammable liquids, with separate protective gas and pressure medium, and its object is to )rovide rotective means for the )i 3% of thc a 'iparatus to be stopped.

In the accol'npanying drawings: Figure l is a vertical section, partly broken away, of an a iparatus embodying my invention; Fig. 2 an enlarged section through the means for controlling the liquid discharge: and Fig. .3 a cross section on line 33, Fig. 1.

The letter (2, indicates the main storage tank, the bottom of which cnnmunicales througl'i pipe 0, with the top of an auxiliary vessel 6. From the latter an upright pipe (1, leads to the discharge faucet (Z, while an elbow pipe f, g, establishes communication between the top of vessel 7), a '1d tank a, to permit the How of the protective gas from vessel 7/, into tank a, during :hc discharge of the liquid from the latter in :o the former. Pipes 0, c, f and y, are inclosedwithin a common jacket ii, that opens irto a Compartment it, provided at the top of tank a. \Vbcrc any of the pipes join the respective l'(:((]')ltl(.ltl') the jacket I; has blind ends. The jacket it is charged with protective gas from llask 2' through a pipe A controlled by cock A1. At a convenient part oi", the compressed air pipe or conduit 6 the thrceovay valve in, is provided, the lover a of s:,id valve being connected by rod 0 to weighted or otherwise depressed piston 79. Piston 7) is movable in cylinder 1 and is placed by lncans of pipe 'I" undcr 'ircssure of the gas ll] jacket /I.. liy this pressure the piston ishcld at the upper conduit.

end of its travel and holds valve m open. To render the piston perfectly tight the cylinder g is filled with a sealing liquidlglycerin), so that the gas does not come into direct contact with the piston. Should the pressure in jacket It fall, by reason of leakage, the piston moves the lever a by gravity and causes valve :m-to cut oil the supply of compressed air and place vessel 0 in com- IlllllllCtllIlOl'l with discharge pipe 8. Continued working of the apparatus is impossible until the leakage has been found and repaired. The relation between the energy with which piston 7) is lowered andthe pressurein the jacket should obviously be such that the piston remains thrust back during normal fluctuations of pressure in the jacket. The possibility of having, any desired degree of pressure in the jacket h allows ofinsuring a safe margin of excess over the pressure of the inflammable liquid at all parts of the conduit. It follows that wherever the leakage Occurs, a sullicient reduction of pressure to reliably operate the cut-oil will take place. and there is no possibility ottheliquid entering the jacket and thence finding an issue through some external leak.

Another improvement of the apparatus consists in constructing the pipe, through which the liquid flows, of the strmigest available material, but making the surrounding pipe of softer material. which melts more readily. If the conduit is attacked with a hatchet, chisel. saw or blowpipe, the n-otective gas pipe is always damaged first, and some time must elapse before the pipe containing the liquid is perforated.

in the drawing the double pipe of the construction first described is shown in cross-section in Fig. 3, forming a safety The pipe c containing the inflammable liquid is composed of steel or other strong material possessing a high melting point. The jacket 1., on the other hand, is of lead or other soft, easily melting material, vapable of resisting the pressure of the protective gas. and the normal strains imposed in laying the pipes, but yielding at once to abnormal strains, and meltim bclorc the pipe 1.: in case of abnormal rise ol temperature. it, therefore, injury occurs to the pipe lb, and causes the safety device to be operated, the liquid has time to flow back through the pipe e before the injury can extend to the latter.

What I claim is: v

1, A device of the character described, comprising a storage tank, an auxiliary vessel, a discharge faucet, pipes connecting the auxiliary vessel with the storage tank and the faucet, a jacket inclosing said pipes and containing a protective gas under pressure, a conduit for admitting a pressure medium to the auxiliary vessel, a cock controlling said conduit, and means actuated by a variation of pressure in the jacket for operating said cock. I

2. A device of the character described, comprising a storage tank, an auxiliary vessel, a discharge faucet, pipes connecting the auxiliary vessel with the storage tank, and the faucet, a jacket inclosing said pipes and containing a protective gas under pressure, a conduit for admitting a pressure medium to the auxiliary vessel, a valve controlling said conduit, a cylinder communieating with .the jacket, and a piston within said cylinder which is operatively connected to the valve. v

3. A device of the character described, comprising a storage tank, an auxiliary vessel, a first pipe connecting the top of the tank with the top of the vessel, a compartment inclosing said pipe at the junction,

thereof with the tank, a discharge faucet, a second pipe connecting the auxiliary vessel with said\ faucet, a protective gas jackettective gas jacket Withsaid valve.

4. A device of the character described,

comprising a storage tank, an auxiliary vessel, a discharge faucet, hard metal pipes connecting the auxiliary vessel with the storage tank and faucet, a soft metal jacket inclosingthefpipes and containing a protective gas under pressure, a conduit for admitting a pressure medium to the auxiliary vessel, a cock controlling said conduit, and means actuated by a variation of pressure in the jacket for operating said cock.
